Hey! Is there an analogue of router.beforeEach() in Framework7 in routers?

In main.js

mounted () {
  this.$f7.view.main.router.on('pageBeforeIn', function () {
    if (userSignIn) {
      console.log('авторизован');
    } else {
      console.log('не авторизован, редиректим на логин пэйдж');
      this.$f7.view.main.router.navigate('/login/',{reloadCurrent: true});
    }
  });
}
